The ground loop represents the foundation of geothermal efficiency. Our maintenance includes comprehensive loop diagnostics using precision flow meters, pressure differential testing across heat exchangers, antifreeze solution concentration testing using refractometers, solution pump operation verification, and thermal performance analysis. We ensure optimal circulation for maximum thermal transfer efficiency.
Maintaining precise refrigerant charge is critical for geothermal efficiency and compressor longevity. We perform detailed refrigerant analysis measuring suction and discharge pressures, superheat and subcooling values, electronic leak detection, and expansion device verification. Even minor charge variations significantly impact performance and equipment life.
The water-to-refrigerant heat exchanger transfers thermal energy between the ground loop and refrigeration system. Any fouling dramatically reduces efficiency. We clean heat exchanger surfaces to remove mineral deposits, biological growth, or debris accumulation, restoring optimal thermal conductivity and system performance.
The microprocessor controls managing your WaterFurnace system require periodic calibration and verification. We review control programming, calibrate temperature and pressure sensors, verify proper staging and capacity modulation, test safety controls, and update software when manufacturer releases improvements.
After completing all maintenance procedures, we provide detailed documentation showing system performance measurements, any issues identified and corrected, recommendations for improvements, and efficiency analysis comparing current performance to baseline specifications. This helps you track your system's condition over time.
